Abstract: A door (1), which can be recessed into a door compartment (2), is fixed on a stop strip (4) which is guided on an upper rail (7a), fastened on a first side wall (6) of the door compartment (2), and on a lower rail (7b), and is fastened on a scissors cross anchored on the said first side wall (6) of the door compartment (2). To make possible a precise mounting of the door hanging before installation and to facilitate an adjustable design, the lower rail (7b) is also fastened on the first side wall (6). The two rails (7a,b) are screwed together with the sleeves, which are screwed in said wall and permit an adjustment of the rail spacing therefrom. The upper anchoring of the scissors cross lies on a fastening part (8), which is connected through the first side wall (6) to an adjustment part in such a way that when the latter is swivelled about a screw connection (9), common to both parts, said fastening part is also taken along. The stop strip (4) bears a roller (16) which, when the door (1) is not in a recessed position, presses against a plastic panel in the region of the front edge of said side wall. A setscrew (24) permits vertical displacement of the stop strip (4) relative to the scissors cross. <IMAGE>

Title: Battery powered in-line amplifier
Inventor: HANON DAVID O
IPC: H04M1/60
Filed: 1990-04-12
Granted: 2000-02-29
Abstract: An in-line amplifier is readily connectable to a standard telephone so as to allow for user adjustment of the volume presented to the receiver portion 15 of the handset 14. The in-line amplifier draws electrical power from a replaceable battery 18 so as to be easily attached to the telephone base unit 12. The in-line amplifier includes a voltage level detector 20, which operates to determine when the battery voltage level has fallen below the minimum operating voltage of the in-line amplifier Ordinarily, the audio signal is passed from the telephone base unit l2 through a controllable amplifier 16 to the receiver portion 15 of the handset 14. However, when the voltage level detector 20 determines that the battery voltage level has fallen below the minimum operating voltage level, a signal is delivered to a low voltage bypass 17, providing a direct electrical path around the controllable amplifier l6 so as to couple the audio signal directly from the base unit 12 to the receiver 15. Within the controllable amplifier l6 a modified class B output stage is employed to provide the current driving capabilities necessary for proper operation of the receiver 15. The class B output stage is modified with a resistor 76 connected between the bases of transistor 62, 64 and their emitters, thereby passing the low level audio output signal from an operational amplifier 48 directly to the receiver 15 during the deadband portion of the class B output stage so as to reduce crossover distortion.

Filed: 1990-08-29
Granted: 1997-12-30
Abstract: An optical fiber interface includes a detector assembly, which may include an integral fiber, for detecting an optical signal carried on a single fiber in an outbound direction and a piezo electric transducer or the like for providing relative movement between the fiber and the detector assembly to produce a modulated return optical signal in reflections of the outbound signal.

Several embodiments modulate the return signal by relative movement either perpendicular to or parallel to the fiber. The perpendicular movement modulates the reflected signal by varying alignment of the fiber and detector assembly, while the parallel movement modulates by varying a Fabry-Perot gap formed between the fiber and the detector assembly. One embodiment includes a cantilever beam of semiconductor material attached to the detector surface. The beam providing an integrated transducer and reflecting surface.

Title: C-mos differential sense amplifier
Inventor: FASSINO MARIO
IPC: G11C7/06
Filed: 1990-12-21
Granted: 1996-01-30
Abstract: A C-MOS sense amplifier detects voltage differences between the signals applied to its inputs in correspondence with transitions of a clock signal.  It comprises a level converter, a sense circuit and a feedback circuit, which are inactive in a first inactive phase of the clock signal, while in a second active phase,  immediately following a clock signal transition, the sense amplifier reaches an operating point necessary to activate the level converter and the sense circuit, and hence a high positive feedback is set up which switches the sense circuit.   Finally, following the corresponding level transition of a delayed clock signal, the feedback signal generated by the feedback block reduces the dissipation of the entire differential sense amplifier to zero.

IPC: H04L12/28
Filed: 1991-04-11
Granted: 2000-01-04
Abstract: Spaced-apart communication controllers connected to a cable-based network place a portable device in communication with the network for transfer of data packets. Each controller communicates with the portable device with packet transmissions through air, and requires registration of the portable device before offering packet transferring services. The registration process involves transmitting a packet from the portable unit requesting a response from controllers, transmitting a response packet from each controller receiving the request, selecting one of the responding controllers at the portable unit according to criteria that enhance data transfer, and transmitting from the portable unit a packet identifying the selected controller to complete registration. The selected controller transmits to other controllers via the network cable a packet confirming the registration. A controller with which the portable device was previously registered responds by de-registering the device and transmitting any stored packets addressed to the device via the cable to the newly selected controller. A power saving protocol is implemented for a battery-operated portable device and adjusted continually to accommodate the rate at which transmissions to the device occur. The power saving arrangement includes disabling the receiving section of the device.
